Final answer:
The claim that Homo heidelbergensis constructed the first shelters at Terra Amata is false; the documented evidence suggests these shelters were built by Homo erectus during the Lower Paleolithic era.
Step-by-step explanation:
The statement that Homo heidelbergensis was the first to construct shelters at the Terra Amata site and that this represents the earliest open-air artificial shelters is false. The shelters at Terra Amata were indeed constructed by early humans, but they were built by Homo erectus during the Lower Paleolithic era, approximately 380,000 years ago. These shelters had a foundation of stones and used vertical posts for support, featuring roofs and walls of sticks and twigs likely covered with straw. However, it is no documented evidence that Homo heidelbergensis, which did modify dwellings in open-air sites and caves, created the first shelters at Terra Amata.
